  Two alpha-D-arabinofuramosyl oligosaccharides (2 and 3) found as constituent parts of the polysaccharide portion from the cell wall of Mycobacterium tuberculosis have been efficiently synthesized via a one-pot glycosylation procedure in which a key step is the chemoselective activation between D-arabinofuranosyl trichloroacetimidate donor 4 and partially protected aryl thioglycosides 5 or 7, respectively.

  beta-D-Arabinofuranose 1,2,5-orthobenzoates with 3-O-acetyl, 3-O-benzoyl, and 3-O-chloroacetyl groups were prepared in an efficient manner starting from readily available crystalline methyl 2,3,5-tri-O-benzoyl-alpha-D-arabinofuranoside, and ring-opening reactions of these compounds with O- and S-nucleophiles were studied. Optimized conditions leading to the formation of the respective monosaccharide adducts (up to 96% isolated yields) and to alpha-(1 -> 5)-linked disaccharide thioglycosides with 5'-OH unprotected (up to 30% isolated yields) were found. Basing on these results, a novel approach for effective differentiation of 3,5-diol system and 2-hydroxy group in arabinofuranose thioglycosides was proposed. The selectively protected derivatives prepared are valuable building blocks for the assembly of linear and branched oligoarabinofuranosides. (C) 2010 Elsevier Ltd. All rights reserved.
• Tuning Effect of Silyl Protecting Groups on the Glycosylation Reactivity of Arabinofuranosyl Thioglycosides

  The tuning effect of silyl protecting groups on the glycosylation reactivity of arabinofuranosyl phenyl thioglycoside donors Is presented. Silyl ethers on the 3-, 5-, and 3,5-positions of the arabinofuranose ring are found to have an arming effect on the donor reactivity, whereas the cyclic 3,5-acetal type protecting groups reduce the reactivity.
